An autologous bone graft substitute composition for inducing new bone formation, promoting bone growth and treating bone defects, a method of preparation thereof, and a method of inducing or promoting bone growth by treatment of a bone with an autologous bone graft substitute composition. The composition includes autologous blood; one or more analogs of an osteogenic bone morphogenetic protein selected from BMP-6, BMP-2, BMP-7, BMP-4, BMP-5, BMP-8, BMP-9, BMP-12, and BMP-13, and combinations thereof; and a compression resistant matrix selected from the group consisting of a bone autograft, bone allograft, hydroxyapatite, tri-calcium phosphate, and combinations thereof. The autologous blood forms a coagulum gel comprising a fibrin-meshwork reinforced with the compression resistant matrix and containing the osteogenic bone morphogenetic protein which is released over a sustained period.

The present invention generally relates to the use of small particles, such as micro particles or nanoparticles, to produce a therapeutic scar such as “trans-mural” scarring or other desired “deep tissue” scarring. In one preferred embodiment, these particles can be delivered to a target location by an implant. More specifically, these particles can be incorporated into the structure of implants or into the coatings on implants. In another preferred embodiment, these small particles can be delivered directly with a catheter by electrophoresis or hydraulic pressure.

A hyperbranched polymer includes a hyperbranched, hydrophobic molecular core, respective low molecular weight polyethyleneimine chains attached to at least three branches of the hyperbranched, hydrophobic molecular core, and respective polyethylene glycol chains attached to at least two other branches of the hyperbranched, hydrophobic molecular core. Examples of the hyperbranched polymer may be used to form hyperbranched polyplexes, and may be included in DNA or RNA delivery systems.

A scaffold for cell culture or tissue engineering is provided. The scaffold includes a fiber web having a three-dimensional network structure, which includes a biodegradable scaffold fiber. Therefore, a microenvironment suitable for migration, proliferation and differentiation of cells to be cultured is created, thereby improving a cell proliferation rate and cell viability. In addition, the scaffold may be easily removed from cells cultured therein without physical/chemical stimuli, and thus the cultured cells may be easily recovered, and is able to be grafted into the body while the cultured cells are included in the scaffold. Moreover, the cultured cells may be cultured to have a similar shape/structure to those of an actual animal body to make it more suitable to be applied in grafting into an in vitro experimental model or animal body.

The present invention relates to the field of biomedical technology, and relates to a composite membrane comprising a decellularized amniotic membrane, a use of the composite membrane, and a method for preparing the composite membrane.
